Bane/Whispers of Doom does not apply 2 curses

I noticed while playing bane with Despair + Temp chains is not always applying both curses. Sometimes its only despair and there is no reason why it shoudnt it cursed with temp chain aswell. The damge therefore is also lower.

I have Whispers of doom allocated, linked temp chains and despair to bane and also have profane bloom.
